Abstract
With the rapid development of information technology and the explosive growth of data volumes, traditional storage systems are increasingly unable to meet demands in terms of flexibility, scalability, and management efficiency. Software-Defined Storage (SDS) has emerged as a solution to address these challenges. This study aims to explore key technologies of SDS to enhance the performance and management efficiency of storage systems. By combining literature review with theoretical analysis, this research focuses on core technologies within the SDS architecture, including virtualization techniques, distributed file systems, automated management mechanisms, and data security protection. The findings indicate that SDS abstracts storage control functions from hardware, achieving centralized management and on-demand allocation of storage resources, thereby significantly improving resource utilization and system flexibility. An innovative storage resource optimization configuration scheme based on intelligent algorithms is proposed, which dynamically adjusts storage resources according to actual loads, effectively reducing energy consumption and enhancing system response speed. Furthermore, a comprehensive SDS test platform was constructed to validate the proposed scheme. Experimental results demonstrate that under various application scenarios, the new scheme exhibits higher resource utilization and superior performance compared to traditional methods, providing strong support for the practical application of SDS and promoting the development of storage technology towards intelligence and efficiency.
